In addition, the conventional soil pressure test only carries out a stress test in one direction, the soil body is used as an anisotropic material, and the soil pressure change data in only one direction is used for evaluating the state of the soil body, so that certain limitation exists. According to the classical soil mechanics theory, the soil pressure and the excess pore water pressure need to be analyzed in a coordinated mode, the soil pressure sensor and the pore water pressure sensor are distributed in a hole dividing mode in the conventional method, even if the soil pressure sensor and the pore water pressure sensor are embedded in the same hole, the soil pressure and the pore water pressure at the same position can be staggered up and down at a certain position, and collected data are not the soil pressure and the pore water pressure at the same position in a strict sense, so that analysis and judgment of the data are influenced. Conventional water and soil pressure sensors are disposable consumables, cannot be recycled, and do not accord with the low-carbon economy concept.
